Javascript regex - how to get text between curly brackets

Question

I need to get the text (if any) between curly brackets. I did find this other post but technically it wasn't answered correctly: Regular expression to extract text between either square or curly brackets

It didn't actually say how to actually extract the text. So I have got this far:

var cleanStr = "Some random {stuff} here";
var checkSep = "\{.*?\}"; 
if (cleanStr.search(checkSep)==-1) { //if match failed
  alert("nothing found between brackets");
} else {
  alert("something found between brackets");
}

How do I then extract 'stuff' from the string? And also if I take this further, how do I extract 'stuff' and 'sentence' from this string:

var cleanStr2 = "Some random {stuff} in this {sentence}";

Cheers!

To extract all occurrences between curly braces, you can make something like this:

function getWordsBetweenCurlies(str) {
  var results = [], re = /{([^}]+)}/g, text;

  while(text = re.exec(str)) {
    results.push(text[1]);
  }
  return results;
}

getWordsBetweenCurlies("Some random {stuff} in this {sentence}");
// returns ["stuff", "sentence"]
